The S-24C0XA is a series of 2-wired, low power 1K/2K/4K-bit EEPROMs with a wide operating range. They are organized as 128-word × 8-bit, 256-word × 8-bit, and 512-word × 8-bit, respectively. Each is capable of page write, and sequential read.
The time for byte write and page write is the same, i. e., 1 msec. (max.) during operation at 5 V ± 10%.
